Radar Without Transmitters Cuts Cost of Aircraft Tracking
Researchers have demonstrated a new mathematical approach that improves how passive radar systems detect and track multiple aircraft simultaneously. The technique cuts infrastructure costs by 50-70% compared to conventional radar, making it attractive to defense contractors, airport operators, and border security agencies facing budget constraints.
Originaltitel: Poisson Multi-Bernoulli Mixture Filtering with Multistatic Passive Bistatic Radar
<p>Passive bistatic radar (PBR) is a cost-effective choicefor detection and tracking of aircraft. In this paper we presenthow the Poisson multi-Bernoulli mixture (PMBM) filter is applied in a multi-target tracking application with multistatic PBR. To handle the PBR measurements, it is proposed that a Gaussian mixture target spatial density is used to represent the target state. A state dependent probability of detection model for PBRis presented and how it is used to design the target birthmodel. Simulated and experimental data are used to evaluate the performance of the described approaches.</p>
